Cargo Bed Stake Pocket Formation for Securing and Supporting a J-Hook Strap

ABSTRACT

Stake pocket formations are secured to a cargo bed frame of a land vehicle such as trailers and flatbed trucks for removably supporting sidewall supporting members. The formations include sidewalls secured to and projecting from the frame and an end wall extending between the sidewalls. An opening extends through the end wall and is adapted to receive the terminal end of a J-hook therethrough. The J-hook is secured to the formation by inserting the terminal end thereof into the pocket placing an upper edge of the end wall into the J-hook gap and rolling/rotating the J-hook thereby inserting the terminal end into the opening. The J-hook cannot be removed from the pocket unless it is rolled/rotated in the opposite direction. While within the stake pocket and without strap tension, the J-hook abuts the trailer frame and formation end wall and is, thereby, maintained within the pocket.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the field of cargo beds of landvehicles such as trailers and flatbed trucks. More particularly, thepresent invention relates to an improved stake pocket formation used ona cargo bed of land vehicles which is adapted both to receive andsupport a side supporting member and to attach a J-hook strap thereto.

2. Background

Trailers are today commonly used by pivotally attaching to and beingpulled behind land vehicles for hauling all sorts of cargo. Flatbedtrucks are similarly used for hauling all sorts of cargo. The trailersand flatbed trucks include a frame or chassis that forms a cargo bedupon which the cargo is loaded and hauled as needed. Sidewalls are oftenprovided and secured along the perimeter of the cargo bed for hauling,for example, bulk materials. When hauling items such as all-terrainvehicles (ATVs), tractors, etc., it is desirable to remove the sidewallsand simply secure such items to the cargo bed with ratchet strapsincluding, for example, straps having J-hooks at their terminal ends.

For selectively securing and removing the sidewalls from the cargo bed,stake pockets can be provided along the perimeter of the cargo bed.Sidewall supporting members such as 2×4 wood stakes are received in andare vertically supported by the stake pockets. The sidewalls are securedto the sidewall supporting members and are, thus, removably secured tothe perimeter of the cargo bed.

SUMMARY OF THE INVENTION

The object of the present invention is to provide an improved stakepocket formation which is capable of receiving and supporting a sidewallsupporting member and which also includes means for easily and reliablysecuring the J-hook of a strap thereto. With the improved stake pocketformation the cargo bed sidewalls can be selectively removably securedto the perimeter of the cargo bed and, when the sidewall supportingmember is removed therefrom, the J-hook of a strap can easily andreliably be secured thereto.

In one form thereof the present is directed to a combination comprisinga cargo bed, a frame supporting the cargo bed and wheels rotatablysecured to the frame and a plurality of stake pocket formations. Eachformation includes a pocket adapted to receive a sidewall supportingmember. Each stake pocket formation includes a pair of sidewalls securedto and projecting from the frame and an end wall extending between thepair of sidewalls. An opening extends through each formation end walland is adapted to receive a terminal end of a J-hook therethrough,whereby a strap having a J-hook at its terminal end may be secured tothe stake pocket formations.

Preferably, the end walls include an upper edge, the opening is definedby side edges separated by a distance of 1.2 to 2.0 inches, and theopening side edges are located at least 0.6 to 1.4 inch below the endwall upper edge.

A J-hook is secured to the formation by inserting the terminal endthereof into the pocket placing the upper edge into a gap of the J-hooklocated between a J-hook shank and fingers and rolling the J-hook andinserting the terminal end thereof through the opening. An overall widthof the J-hook is greater than a width of the pocket whereby, when aJ-hook is located within the pocket and the J-hook strap is not intension, the J-hook is supported and maintained within the formation.

Preferably, each stake pocket formation further includes an attachmentwall extending from each of the sidewalls, and the attachment walls areattached to the frame whereby the sidewalls are secured thereto. Theformation attachment walls, sidewalls and end wall are integrally formedwith one another.

An A-frame jack tube 38 issecured to the tongue 34 and is adapted to receive a standard gearboxand extension tube (not shown) for supporting and selectively raisingand lowering the tongue 34 and, hence, the forward end of the trailer10.

Trailer 10 can further include wheel fenders 40 secured to the frame 12and positioned over the wheels 18. Lights brackets 56 are also securedto and extend outwardly from the frame 12 whereupon trailer lights (notshown) can be mounted.

Left and right sidewalls 42, 44, front wall 46 and rear tailgate 48 canalso be provided and secured to the frame 12. The left and rightsidewalls 42, 44 can be secured with sidewall supporting frame members54 which are secured to and extend upwardly from the frame 12. A sparewheel 52 can be detachably secured to one of the sidewall supportingframe members 54.

As seen in FIG. 2 wherein the sidewalls, front wall and tailgate 42, 44,46 and 48 have been omitted, wheels stops 50 can be provided at theforward end of the frame 12 for abutting the wheels of vehicles such asATVs and lawn tractors being carried on the trailer 10 without a frontwall 46. Combination stake pockets and strap securement members 58 canalso be provided and secured to the frame 12. Securement members 58 areadapted to slidingly receive and support a 2×4 wood member in a positionsimilar to sidewall supporting frame members 54 and securing othersidewalls thereto as may be desired. Advantageously, securement members58 are also adapted for selectively attaching thereto double J-hooks ofcommon ratchet straps.

Trailer frame 12 is made by assembling and securing together with rivetsor other suitable fasteners: left and right side structural members 60,62; front end structural member 64; rear end structural member 66;crossbeam members 68; and, torque tube 70. The left and right terminalends 72, 74 of the front end structural member 64 are secured to therespective front terminal ends 76, 78 of the left and right sidestructural members 60, 62. The left and right terminal ends 80, 82 ofthe rear end structural member 66 are secured to the respective rearterminal ends 84, 86 of the left and right side structural members 60,62. The crossbeam members 68 are secured, at their terminal ends 88, toand between the left and right side structural members 60, 62. Thetorque tube 70 is also similarly secured, at its terminal ends 90, toand between the left and right side structural members 60, 62. The frontend structural number 64, rear end structural number 66, cross beammembers 68 and the torque tube 70 are, hence, secured between and extendtransverse to the left and right side structural members 60, 62.

As best seen in FIG. 9, the left and right side structural members 60,62, when viewed in cross-section, comprise: a U-shaped portion includinga branch leg 92 and an attachment leg 94 integrally formed with andextending from a base section 96; and, an L-shaped portion including abranch leg 98 integrally formed with an attachment leg 100. The branchleg 92 of the U-shaped portion is integrally thrilled with the branchleg 98 of the L-shaped portion. At their front terminal ends 76, 78, theside structural members 60, 62 each include a tab 102 integrally formedwith and extending generally perpendicular from their base section 96.At their rear terminal ends 84, 86, the side structural members 60, 62each include an upwardly bent element 104 formed by cutting a V-notch104 between the base section 96 and attachment leg 94 and bending theattachment leg 94 portion adjacent the V-notch at an angle from theattachment leg 94.

The crossbeam members 68 are generally Z-shaped in cross-section andcomprise a central web section 106 and flange sections 108 which areintegrally formed therewith and extend generally perpendicular from thecentral web section 106.

The front end structural member 64, in cross-section, is generallyU-shaped having a lower leg 110 and an upper leg 112 integrally formedwith and extending from a base section 114. The terminal portion of theupper leg 112 is bent over onto itself thereby forming an overlappingarrangement including an interior section 1116 integrally formed withthe upper leg 112 along a terminal edge 118. Upper leg 112 and interiorsection 116 are adjacent and parallel to one another. As best seen inFIG. 7, an abutment section 120 is integrally thrilled with the interiorsection 116 and extends generally perpendicular therefrom. The abutmentsection 120, as shown in FIG. 11, does not extend to the left and rightterminal ends 72, 74 for thereby placing the terminal ends of the branchlegs 92 parallel and adjacent the terminal ends of the upper leg 112 andsecuring to one another as further described hereinbelow.

The rear end structural member 66, in cross-section, is also generallyU-shaped and includes an upper panel 122 and toe panel 124 integrallyformed with and extending from a rear panel 126. Upper panel 122 isgenerally perpendicular to the rear panel 126, whereas the toe panel 124extends at an angle therefrom as best seen in FIG. 10. At each of theleft and right terminal ends 80, 82, a side panel 128 is integrallyformed with and extends generally perpendicular from the upper panel122. A bottom side panel section 130 is integrally formed with andextends generally perpendicular from each of the side panels 128. Bottomside panel sections 130, as best seen in FIG. 10, extend at an anglerelative to the upper panel 122 and are generally parallel with toepanel 124 and the upwardly bent elements 104 of the left and right sidemembers 60, 62.

The torque tube 70, in cross-section, generally comprises a firstU-shaped portion 132 nested and secured by welding with a secondU-shaped portion 134. The first U-shaped portion 132 includes first andsecond legs 136, 138 extending from and integrally formed with a basesection 140. Brim extensions 142 are integrally formed with and projectgenerally perpendicular from the terminal ends of each of the first andsecond legs 136, 138. The second U-shaped portion 134 includes first andsecond legs 144, 146 extending from and integrally formed with a basesection 148. As best seen in FIG. 7, the first U-shaped portion 134 isreceived within and nested in the second U-shaped portion 132 placingthe first leg 136 of the first U-shaped portion 132 adjacent first leg144 of the second U-shaped portion 134 and placing the second leg 138 ofthe first U-shaped portion 132 adjacent the second leg 146 of the secondU-shaped portion 148. U-shaped portions 132, 134 are secured to oneanother by welding as indicated by welding beads 150 located at thebends between the first and second legs 136, 138 and the brim extensions142 and the bends between the first and second legs 144, 146 and thebase section 148.

Referring now more particularly to FIGS. 13-17, in cross-section, thetongue 34 is tubular shaped and is made up of a rectangular component152 having a longitudinal opening 154 and a flat sheet component 156which fills the longitudinal opening 154 and is welded to therectangular component 152. The rectangular component essentiallycomprises a U-shaped portion including sidewalls 158 integrally formedwith and extending from a top wall 160. Flange sections 162 areintegrally formed with and extend from the ends of the sidewalls 158toward one another. Flange sections 162 are coplanar and thelongitudinal opening 154 is located therebetween. The sheet component156 is secured to the flange sections 162 by welding as indicated bywelding beads 164 located at the terminal edges of the flange sections162.

A hole 166 is provided in the top wall 160 of the rectangular component152 and the jack tube 38 extends therethrough and also through thelongitudinal opening 154 as best seen in FIG. 16. Jack tube 38 includesa triangular mounting plate 168 with bolt holes 170 extendingtherethrough adjacent each of the triangle corners. One corner 172 ofthe triangular plate 168 is bent and extends perpendicular therefrom forthereby placing the bent corner 172 and the bolt hole 170 thereofadjacent one of the sidewalls 158 of the rectangular component 152. Theother corners of the triangular mounting plate 168 and bolt holes 170thereat are thereby located adjacent the top wall 160 of the rectangularcomponent 152. The jack tube 38 is thereby secured to the tongue 34 withtwo bolts (not shown) each of which extend through a bolt hole 170 andthrough the top wall 160 of the rectangular component 152, and one boltnot shown) which extends through the bolt hole 170 of the bent corner172 and through the sidewall 158 of the rectangular component 152. It isnoted that the ball hitch coupling assembly 36 is also secured to thetongue 34 with bolts (not shown) which extend through holes 174therethrough and aligned holes (not shown) which extend through thesidewalls 158 of the rectangular component 152.

The tongue 34 is pivotally secured to a trailer tongue pocket 176 whichis, in turn, secured to the trailer frame 12. Pocket 176, incross-section, is generally top hat shaped and comprises a top wall 178,sidewalls 180 integrally formed with and extending therefrom and brimportions 182 integrally formed with and extending perpendicular from theends of the sidewalls 180. At each of its terminal ends, pocket 176 isprovided with tabs 184 which are integrally formed with and extendperpendicularly upwardly from the top wall 178. Pocket 176 is providedwith front holes 186 and rear holes 188 which extend through thesidewalls 180.

The rear portion of the tongue 34 is received within the tongue pocket176 in a nested towing position as best seen in FIG. 13. In the nestedtowing position, holes 190 extending through the sidewalls 158 of thetongue 34 are aligned with the front holes 186 of the tongue pocket 176and a removable pin (not shown) is provided extending therethrough.Also, holes 192 extending through the sidewalls 158 near the rearterminal end of tongue 34 are aligned with the rear holes 188 of thetongue pocket 176 and a bolt (not shown) is provided extendingtherethrough. As should now be appreciated to one skilled in the art,the removable pin can selectively be removed from the aligned holes 186,194 thereby allowing the tongue 34 to pivot about the bolt extendingthrough holes 188, 192 and, while tongue 34 remains generallyhorizontal, allow the trailer frame 12 to also pivot about the axle 16and thereby place the trailer 10 in a tilted position at an angle fromthe horizontal. In the tilted position, the rear end structural member66 is in contact with the ground whereby, for example, vehicles such asall-terrain vehicles (ATVs) and lawn tractors can be driven onto or offthe trailer bed 32 and/or items on the trailer bed 32 can be dumped offtherefrom. In the tilted position, the toe panel 124 and bottom sidepanel sections 130 of the rear end member 66 are placed generallyhorizontal and in contact with the ground.

As mentioned hereinabove, in accordance with the principles of thepresent invention, the several structural components/members, includingcomponents/members 34, 42, 44, 46, 48, 50, 54, 58, 60, 62, 64, 66, 68,70 and 176 are made of sheet metal and are then assembled for making thetrailer 10. More particularly, the several structural components/membersare made by cutting desired shapes which are diagrammatically indicatedin FIGS. 18 and 19 with the numeral 190 from larger sheets of metal 192and/or larger sheets of metal 192 provided on a roll. Sheet metal sheets192 and rolls 194 are made of steel and are provided with a protectivecoating against rust on both sides thereof. Preferably, the protectivecoatings are galvanized coatings of zinc, aluminum or a combination ofzinc and aluminum. The desired shapes 190, after cutting, are thereforealso galvanized on both sides thereof. The sheet metal sheets 192 androlls 194 will typically be 10 to 16 gauge in thickness and, mostpreferably, will be 12 to 14 gauge in thickness. Preferably, the desiredshapes 190 are cut from the sheet metal sheets 192 by laser cutting,although other cutting methods such as shearing or punch pressing may beemployed as well. Preferably, when cutting the desired shapes 190 fromsheets 192, fastening holes and other holes and openingsdiagrammatically depicted by the numeral 198 are also cut or punchedthrough the desired shapes 190. It is noted that, after cutting, thesheet metal underlying steel at the cut edges 196 is exposed and subjectto rust. However, any such rusting will be quite slow and will notmarkedly affect the structural strength and appearance of the severalcomponents/members during the anticipated life of the trailer 10.

The desired shapes 190, as can be appreciated by one skilled in the art,have a perimeter edge 196 outline having a desired shape, e.g., width,length, etc., whereby the several components/members can be made byfurther bending and shaping. For example, as shown in FIG. 20, thedesired shape 190 is bent as indicated “down 90°” and “up 90°” at thebend lines between the central web section 106 and the flange sections108 for thereby forming a cross beam member 68. Also by way of example,as shown in FIG. 21, the desired shape 190 is bent as indicated forthereby forming a right side structural member 62. Also as indicated inboth FIGS. 20 and 21, the several fastening holes and openings 198 thatwere cut or punched in the desired shapes 190 form the fastening holesand other openings whereby the several components/members can beassembled by aligning such fastening holes and openings as needed andsecuring the several components/members to one another with fastenersinserted therethrough. Preferably, the several components/members areassembled using rivets 200 and, more preferably, using blind rivets. Itis noted that throughout the several views of the drawings thecomponents/members, whether assembled to one another or not, for claritypurposes, are shown and depicted only with their fastening holes andopenings 198 and without the fastening rivets 200.

Referring now again to FIGS. 3-12, it can be seen that the frame 12 isassembled by securing the crossbeam members 68 transversely between theleft and right side structural members 60, 62. In this regard, theterminal ends 88 of crossbeam members 68 are inserted into the left andright side structural members 60, 62 placing their upper flange 108adjacent the attachment leg 100 and their lower flange 108 adjacent theattachment leg 94. At each crossbeam terminal end 88 the upper flange108 thereof is attached to the attachment leg 100 with one or morerivets 200 and the lower flange 108 is attached to the attachment leg 94with one or more rivets 200 (see example thereof in FIG. 7).

The torque tube 70 is attached to the left and right side structuralmembers 60, 62 similar to the crossbeam members 68. The torque tubeterminal ends 90 are inserted into the left and right side structuralmembers 60, 62. The terminal ends of the torque tube brim extensions 142are thereby placed adjacent and secured to the attachment legs 100 withone or more rivets 200. Also, the terminal ends of the torque tube basesection 140 are thereby placed adjacent and secured to the attachmentlegs 94 with one or more rivets 200 (see example thereof in FIG. 7).

The left and right terminal ends 72, 74 of the front end structuralmember 64 are secured to the respective front terminal ends 76, 78 ofthe left and right side structural members 60, 62 as best shown in FIGS.11 and 12. Here, the branch legs 92 are placed adjacent to andoverlapping with the upper leg 112 and secured to one another with oneor more rivets 200 (not shown). The tabs 102 are placed adjacent to andoverlapping with the base section 114 and secured together with one ormore rivets 200 (not shown). Also, the attachment legs 94 are placedadjacent to and overlapping with the lower leg 110 and secured togetherwith one or more rivets 200 (not shown). As shown in FIG. 7 the trailerbed 32 rests on and is secured with screws (not shown) to the crossbeammembers 68 and the torque tube 70. The trailer bed 32 also extendsbeyond the terminal edge 118 and under the interior section 116 of thefront end structural member 64 thereby providing a generally smoothtransition between the upper surface of the trailer bed and the uppersurface of the upper leg 112 of the front end structural member 64.

The left and right terminal ends 80, 82 of the rear end structuralmember 66 are secured to respective rear terminal ends 84, 86 of theleft and right side structural members 60, 62 as shown in FIGS. 3-6 and10. In this regard, the bottom side panel sections 130 are placedadjacent to and overlapping with the upwardly bent elements 104 and aresecured together with one or more rivets 200 (not shown). The sidepanels 128 are placed adjacent to and overlapping with the base section96 and are secured together with one or more rivets 200 (not shown).Also, the upper panel 122 is placed adjacent to and overlapping with thebranch leg 92 and is secured thereat with one or more rivets 200 (notshown). As best seen in FIG. 10, the trailer bed 32 extends over thecrossbeam member 68 located close to the rear terminal ends 84, 86 ofthe left and right side members 60, 62 and under and adjacent to theupper panel 122 of the rear member 66. Screws 202 extend through andsecure together the upper panel 122, the trailer bed 32 and the flange108 of the cross beam member 68.

The tongue pocket 176 is secured to the frame 12 with its top wall 178located adjacent to the base section 140 of the torque tube 70 and thelower leg 110 of the front end structural member 64. In this position,the tongue pocket rear tab 184 is adjacent and secured to the second leg138 of the torque tube 70, and the tongue pocket front tab 184 isadjacent and secured to the base section 114 of the front end structuralmember 64.

As mentioned hereinabove, combination stake pockets and strap securementmembers 58 are provided and are secured to the frame 12. Typically,securement members 58 are attached to the left and right side members60, 62 as shown in FIG. 6, although it is contemplated that they canalso be provided and attached to the front end member 64 and rear endmember 66. The stake pockets and strap securement members 58 can also beprovided and secured on other land vehicles such as flatbed trucks. Itis noted that, although the combination stake pockets and strapsecurement members 58 are described herein for use along the perimeterof a trailer bed/cargo bed 32, it should be understood that theinvention is not so limited and that the stake pocket and securementmembers 58 can also be used along the cargo bed perimeter of other landvehicles such as, for example, flatbed trucks.

Sidewall supporting members such as 2×4 wood members or other similarsidewall supporting members made of other materials and dimensions (notshown) are received in and are vertically supported by the securementmembers 58 in a known and customary manner. Similar to the sidewallsupporting frame members 54, the 2×4 wood members and/or such othersidewall supporting members are typically used, in a known and customarymanner, for supporting the cargo bed sidewalls (not shown) as may beneeded or desired.

Referring now more particularly to FIGS. 22-27, the stake pockets andstrap securement members 58, in accordance with the principles of thepresent invention, include means for selectively attaching theretocommon cargo J-hooks such as, for example, as shown in FIG. 24, a doubleJ-hook 204 which is attached at a terminal end 706 of a cargo strap 208.

As shown in FIG. 24, J-hook 204 is made by bending steel rod into ashape including a strap arm 210. Legs 212 extend from the terminal ends214 of the strap arm 210 and are united to one another at the bend 216thereby forming a Y-shaped back wall or shank 218. Fingers 220 areunited/adjacent one another and extend from a bend 216 to a point orterminal end 222. Legs 212 can be joined to one another and fingers 220can be joined to one another as shown by welding 224 or other suitablemeans for added strength in a known and customary manner. The exteriorsurfaces of the J-hook 204 are typically treated with a protectivecoating for preventing rust.

Cargo strap 208 is made of nylon or other suitable materials and istypically secured to or is adapted to be secured to a ratchet strap (notshown) for tensioning the strap and securing cargo to the trailer in aknown and customary manner. As shown in FIG. 24, cargo strap 208 extendsaround the strap arm 210 and is secured onto itself with stitching 226or other suitable means. Accordingly, cargo strap 208 is pivotallysecurely attached to the J-hook 204.

The steel rod forming the J-hook is about 7/16 inch diameter.Accordingly, when fingers 220 are placed adjacent one another, the widthW of the terminal end 222 is about ⅞ inch plus any gap 228 that may beprovided therebetween. Also, as best seen in FIG. 26, the fingers lengthFL is about 1⅝ inch; the shank length SL is about 2 15/16 inch; thethroat depth TD is about ⅞ inch; and, the gap G between the shank 218and fingers 220 is about 15/16 inch.

The stake pockets and strap securement members 58 comprise stake pocketformations generally designated by the numeral 230. Stake pocketformations 230 include sidewalls 232 an end wall 234 extending generallyperpendicular to and between the sidewalls 232 and attachment walls 236extending generally perpendicular to the sidewalls 232 and in adirection away from the end wall 234. Essentially, sidewalls 232 and endwall 234 form a U-shape and, with the attachment walls 236, form a tophat shape. Fastener holes 238 are provided through the attachment walls236. Bolts, rivets or other suitable fasteners (not shown) extendthrough the fastener holes 238 and into the frame 12 for securing thestake pocket formation 230 thereto. Stake pocket formation 230 can alsobe secured to the frame 12 by welding the attachment walls 236 to theframe 12, and/or by welding the sidewalls 232 themselves directly to theframe 12. Accordingly, with the stake pocket formation secured to theframe 12 as described and shown, the sidewalls 232 project generallyperpendicular from the frame 12.

Preferably, the attachment walls 236, sidewalls 232 and the end wall 234are integrally formed from a single sheet of steel by bending andcreating the formation 230 as shown. Also preferably, the thickness ofthe steel sheet will typically be 10 to 16 gauge and, most preferably,will be 12 to 14 gauge, although it is contemplated that much thickersteel could also be used as may be needed or desired. The steel sheetsare also provided with a protective coating against rust on both sidesthereof similar to the other trailer components as describedhereinabove.

As best seen in FIG. 22, the attachment walls 236, sidewalls 232 and endwall 234 have a height H of about 3.5 inches. The pocket length PLbetween the sidewalls 232 is slightly greater than 3.5 inches, and thepocket width PW between the trailer frame 12 and the end wall 234 isslightly greater than 1.5 inch. Accordingly, the stake pocket formation230 forms a stake pocket 240 which is rectangular shaped and is slightlygreater than about 1.5 inch by about 3.5 inches wherein a standard 2×4wood member can be slidingly received.

An opening 242 extends through the end wall 234 and is adapted toreceive therethrough the terminal end 222 and fingers 220 of the J-hook204. Opening 242 is defined by side edges 244 which are preferablyseparated by a distance of 1.2 to 2.0 inches. Most preferably, opening242 is circular shaped (the side edges 244 form a circular shape) asshown having a diameter D of about 1.6 inch.

Opening 242 is generally centrally located between the sidewalls 232.Opening 242 is also located below an upper edge 246 of the end wall 234a distance B which is preferably 0.6 to 1.4 inch and, most preferably,about 1.0 inch. That is, the side edges 244 of the opening 242 arelocated at least 0.6 to 1.4 inch below the upper edge 246 and, mostpreferably, the side edges 244 are located about 1 inch below the upperedge 246.

Referring now more particularly to FIGS. 25-27 wherein the use of thestake pocket formation 230 is depicted, a J-hook 204 is shown, forclarity purposes, without the cargo strap 208. For securing the J-hook204 to the formation 230, as shown in FIG. 25, the fingers 220 andterminal end 222 thereof are first inserted into the stake pocket 240 byplacing the end wall upper edge 246 in the gap G between the shank 218and the fingers 220. By further rolling/turning the J-hook 204 asindicated by arrow R, the fingers 220 and terminal end 222 thereof areinserted into and through the opening 242 as shown in FIG. 27. As can beappreciated, in the position shown in FIG. 27 the cargo strap 208 can betightened/placed in tension such that the J-hook 204 is pulled in adirection as indicated by arrow F. With the cargo strap 208 in tension,the end wall 234 above the side edges 244 is received within the gap Gof the J-hook 204 with the side edge 244 abutting the bend 216 of theJ-hook 204. As should now also be appreciated, so long as the cargostrap 208 remains in tension, the J-hook 204 is securely retained in theposition as shown in FIG. 27.

It has been found that the distance B relative to the J-hook gap G andthroat depth TD must be coordinated and sized as described hereinaboveso that, as the J-hook 204 is rolled into the stake pocket 240 asindicated by arrow R, the terminal end 222 thereof will be receivedthrough the opening 242. If the distance B is too large relative to theJ-hook gap G and throat depth TD, the terminal end 222 will hit the endwall 234 rather than the opening 242. On the other hand, if the distanceB is too small, the strength thereof may be insufficient forwithstanding the force exerted thereon by the J-hook.

Also advantageously, while the cargo strap 208 is placed over and/oraround cargo on the trailer or the cargo strap 208 is otherwise not intension, the J-hook 204 which has been placed into the stake pocket 240will not fall therethrough but, rather, will fall into and will bemaintained in the position as shown in FIG. 26. That is, without atension force F, the J-hook 204 is gravitationally pulled downwardlyinto the stake pocket 240 until the shank 218 abuts the trailer frame 12and the fingers 220 abut the side edges 244 of the opening 242. In thisregard, it has been found that the J-hook steel rod diameter, gap G andpocket width PW must be coordinated so that, without a tension force F,the shank 218 will abut the trailer flame 12 and the fingers 220 willabut the side edges 244 of the opening 242. More particularly, theoverall width OW of the J-hook, which is about two times the roddiameter plus the gap G distance, is coordinated to be greater than thepocket width PW.

Finally, as should now also be appreciated, the J-hook cannot be removedfrom the stake pocket 240 by merely pulling the strap 208 thereofvertically upwardly. Rather, for removing the J-hook from the stakepocket 240, the J-hook must be rolled in the opposite direction of arrowR around and over the end wall upper edge 246.
